我对cypress / javascript / jquery还是比较陌生,非常感谢您的帮助!我正在尝试一种使用cypress来访问iframe中的元素的方法,该方法在这里建议使用:https://github.com/cypress-io/cypress/issues/136#issuecomment-525994895。我的.its命令出现了柏树错误,而getInDocument自定义命令中出现了后续错误。
这是正在测试的html代码的摘录:
<iframe id="iframeDiag" style="width:100%;height:100%;border:none;padding:0px;z-index:1001;" src="https://<snip>">
#document
<snip>
<button _ngcontent-c11="" class="btn btn-md pointer btn-primary" type="button">Next</button>
<snip>
</iframe>
这是柏树代码:
cy.get("#iframeDiag")
.iframeLoaded()
.its('document')
.getInDocument('button:contains(Next)')
.trigger('click')
.get成功。 .its有此错误:
cypress_runner.js:126133 Uncaught TypeError: Cannot convert object to primitive value

at Object.emit (cypress_runner.js:101958)
at Object. (cypress_runner.js:100786)
我应该关注TypeError吗?从表面上看,这似乎是一个柏树错误,但我意识到它可能是受测试的应用程序代码。
还是可以忽略掉它,我应该专注于.getInDocument命令中的选择器?
任何帮助将不胜感激!谢谢!

嗯,实际上,我认为没有用的东西。如果有人看到该问题,则会进行尝试。我不能赞扬这种方法的创建者,因为我不记得我从哪里得到的(沿着兔子洞!):
it ('Checking Accessibility', () => {
// inject axe into iframes
cy.window()
.then((win) => {
var iframe = win.document.getElementsByTagName('iframe')[0];
console.log('Inject axe into iframe '+iframe.id);
var script = iframe.contentWindow.document.createElement("script");
script.src = '../js/axe.min.js';
script.type = 'text/javascript';
iframe.contentWindow.document.body.appendChild(script);
//wait(6000);
const axe = require('axe-core');
return win.axe.run(iframe, { iframes: true} );
})
.then(({ violations }) => {
if (violations.length) {
cy.wrap(violations, { log: false }).each(v => {
Cypress.log({
name: 'a11y error!',
consoleProps: () => v,
message: `${v.id} on ${v.nodes.length} Node${
v.nodes.length === 1 ? '' : 's'
}`
})
})
}
return cy.wrap(violations, { log: false })
})
.then(violations => {
assert.equal(
violations.length,
0,
`${violations.length} accessibility violation${
violations.length === 1 ? '' : 's'
} ${violations.length === 1 ? 'was' : 'were'} detected`
)
})
});
我确实遇到了可访问性冲突,所以ax可以正常工作,但是iframe内什么都没有(并且iframe内的冲突确实存在)。
